The flesh-eating drug, Krokodil, has been making headlines in Russia and the United States for its horrifying effects on those who have tried using it.

Various reports indicate that Krokodil has been reportedly spotted in Canada. According to Ontario health workers, they have seen suspected cases of the flesh-eating drug Krokodil on the streets.

Reports from the Niagara Regional Police said authorities are investigating two cases linked to Krokodil. This is the first time that the existence of the flesh-eating drug has been made public in Canada.

Two Canadian men have been hospitalised in St. Catherines in the last two weeks with sores on their bodies believed to be the effects of Krokodil. Another case was reported in Niagara Falls. Brenda Horton, who works at the Drug Treatment Centre, said one patient described feeling a burning sensation coming from the inside out. Ms Horton said the drug left holes on his arms.

Outreach workers in Canada have been on high alert to prepare for more Krokodil-related cases.

Krokodil is created by boiling codeine tablets with paint thinner, lighter fluid and gasoline. The resulting drug reportedly gives users the same high as they get when using heroin but at a cheaper price. Once the drug is injected, the impurities in Krokodil can cause extensive damage to human tissues. This will ultimately cause human flesh to rot away.

Doctors in the U.S. specifically in Illinois and Arizona have reported treating patients who were users of the flesh-eating drug Krokodil. The drug is apparently new to the United States. The flesh-eating drug was reported spreading in the U.S. after a number of Krokodil-related cases was reported to authorities.

The Drug Enforcement Agency (DEA) has released a statement for the public to be aware of Krokodil, a drug allegedly from Russia. Jack Riley, Special Agent-in-Charge of DEA Chicago Field Division, said the agency was concerned about the news of patients being treated at Presence St. Joseph Medical Center.

The patients were reportedly suffering from symptoms due to consistent use of Krokodil. Mr Riley said the DEA's task force members and DEA agents were on the streets to investigate the source. He assured the public that agents were already working to track any leads.

He said the DEA will not know the extent of what the drug is all about until the agency can locate the source and the drugs in question. Mr Riley said that the DEA is sure that Krokodil is "extremely dangerous" and the agency will do its best to stop the trafficking.
